Improved Ancient City armor loot pool

Currently, ancient city loot contains a variety of items, some more useful than others.

After raiding an ancient city, though, I noticed that the only kind of armor they can have is iron and diamond leggings. So now I have 6 enchanted iron leggings and 5 enchanted diamond leggings, all with extremely similar enchantments (protection 4, unbreaking 3, mending, curses, etc). And no helmets, chestplates, or boots.

There is no variety in the kind of armor you get at all. I think this is silly. Include helmets, chestplates, and boots in the loot pool--just so it's not all leggings. Surely the ancient cities' best warriors wore more than just pants, right?
